This is a high-quality seal kit designed for the arm cylinder of Volvo excavators, ensuring the integrity of the hydraulic system by preventing fluid loss and maintaining optimal pressure. Manufactured to meet rigorous OEM quality standards, these seals provide excellent durability and resistance to wear, heat, and contamination. Operators may notice hydraulic fluid leaking from the arm cylinder, sluggish arm movement, or the arm drifting downwards when the cylinder seals begin to fail.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Visible hydraulic fluid leaks around the arm cylinder rod are the primary indicator of seal failure. This leakage will lead to a gradual loss of hydraulic pressure, causing the arm to move slower and with less force. If ignored, significant fluid loss can compromise the entire hydraulic system's performance and potentially damage the cylinder's internal surfaces.
Thoroughly clean the cylinder barrel and piston rod before installing the new seals to prevent any contamination that could cause premature failure. Ensure seals are correctly oriented and lubricated with clean hydraulic oil to avoid damage during insertion.
Check the hydraulic oil level and filter condition, and inspect the arm cylinder rod for any signs of pitting or scoring before installing the new seal kit.
